本文对Wigley船在入射波中的粘性绕流进行了数值模拟。作者之一已经开发了一个CFD程序SURF，该程序在非结构网格系统中使用伪压缩性假设求解Navier-Stokes方程。在本工作中，我们修改了程序，以计算船舶在入射波中的绕流。同时为了处理船舶运动，我们将动网格系统引入SURF。求解粘性流场入射波问题的优点之一是可以计算螺旋桨周围的粘性流场。本文研究了船舶在入射波中运动和不运动时，运动对尾流的影响。然后进行了数值计算和讨论。
This paper presents viscous flow simulation around a Wigley ship running in incident waves. One of the authors has been developing a CFD code SURF, which solves the Navier-Stokes equations in unstructured grid system with pseudocompressibility assumption. In the present work, we modify the code to compute the flows around ship running in the incident waves. Also in order to treat ship motions, we introduce moving grid system into SURF. One of advantages to solve viscous flows of incident wave problem is to evaluate viscous flow field around propeller. In the paper, we show the influence of ship motion on wake when the ship runs in incident waves with and without ship motion. Then numerical results and discussions are done.
